GRILLE AND METHGD 0F CONSTRUCTING' SAME.

Application filed July 17, 1915.

To all whom it may concern:

Be it known that 1, CHARLES G. DUFFY, a citizen. of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Grilles and Methods of Constructing Same, of which the follow- .ing is a. specification.

ll lfy qaresent invention relates to improvements in grilles and methods of constructing same, the features and advantages of which will be apparent to those skilled in the art from an understanding of the following description in connection with the drawings.

In. the latter. Figure 1. is a rear elevation of a grille suitable for a cabinet door or other closure, portions being broken away or shown in sectionbettcr to disclose the construction; Fig. 2 is a front view of one end of the same grille; Fig. 3 is an enlarged sectional view on the line 33 in Fig. 1 looking'in the direction of the arrows; Fig. l is the same on the line 4l"l in Fig. 1; Fig. 5 is the same on the'line 5-5 in Fig. 1; Fig. 6 is the same on the line 6-6 in Fig. 2; and Fig. 7 is an enlarged cross sectional view of a detail.

In the drawings, 1-1 are the rails and 22 the stiles which are mitered together to form the frame of the grille. The splats 3 are sawed out of wood and 4: are molded or pressed ornaments made of a non-fragile composition. Thus a composition may be used comprising wood-fibers and a suitable binder. 40 is a large center ornament made similarly ofcomposition. V

The splats 3 are united in groups or units by end continuations or tongues 3* which project into grooves 1 formed longitudinally, one on the inside of each rail 1. In the same way, the center ornament 4:0 is long enough at the ends to projectinto these grooves and is held thereby like the splats in the frame. The tongues of the aforesaid parts are forced against each other endwise in the groove by the end contact of the stiles 22 (see Fig. 1) when the latter are framed to the rails.

The inside 3* of the tongues may be cut to be flush with thefinished inside edge of the rails and will remain substantially so, in spite of changes in the wood due to atmospheric conditions because the splats and Specification of Letters Patent.

tongues are cut lengthwise 01" the grain and in this direction the changes are slight.

On the other hand, I have avoided grooves on the inside of the stiles 2-2 to receive straight splats which might be received like the aforesaid tongues into said grooves. This additional or alternative way of securing the splats. in the frame I have dis covered to be objectionable because the shrink and swell of the splats being transverse to their length, the even or flush finish previously referred to cannot be secured and maintained between the inside of the tongues and the inside of the frame.

The ornan'ients 4c are inserted between the splats and while most of their outline is out of contact with the splatsrto give an open airy, carved appearance to the grille, nevertheless projections are suitably provided or the splats are suitably shaped to the ornamerits, so that they are gripped or held be tween the splats. 1

in addition to glue applied at these points of contact between the ornaments and the splats and their tongues, l'provide the following means and method to secure them in their inserted positions: I make saw-cuts 5 across the wide portions of the ornaments and slightly under-cut the sides of the cuts. I then take metal staples 6 whose crosspieces are slightly too thick to pass through the mouth of the saw-cuts. The grille is then laid face down on a support in contact with the face of the splats. One of the ornaments is then inserted face down in proper position between its pair of splats. A pair of holes are then formed by a suitable two pointed punch in the splats 'to receive the points of the prongs of the staple. The staple is then driven with a hammer until the prongs are fully driven into the splats and until the cross-piece of the staple is squeezed down into the saw-cut in the ornament (compare Fig. 7.) The result is that the ornament is securely attached to the staple and the staple to the splats. Further the splats are drawn together by the stapling operation due to the convergence of the prongs of the staple driven into the aforesaid holes formed with this object in view. Glue having previously been applied to the contact points between the ornament and the splats, the net result I find is that I the inserted ornament is strongly and firmly secured in place. The deseribedstaples do not show from the front of the grille (Flg. '2) because care is taken to locatethem across the wide parts of the ornaments as in Fig. 1.

This completes'the grille except if desired, a Sllk fabric or other backing 7 may I be provided. To mount this so as to be taut frame which is now ready to be inserted silk-side forward into'its recess in the llllQ- frame, and secured therein by the screws 9.

Cross-pieces 8 are further. preferably provide'd' on this back-frai'ne to which the fabric 3 will also be glued as aforesaid, said-crosspieces being located behind the fabric and the splats inthe grille, of course. cannot be seenfrom the front.

fTh'e result of this invention is a grille w iclrhas tl e appearance of a hand Carved grille and which-is superior in the respects that it is much stronger and more durable as well as much cheaper.

What I claim is r 1. A grille comprising splats, a molded ornament inserted between said splats, the outline of said ornament having a portion which bridges the space between them, and attaching means secured to the back of both the splats and the ornament at said bridging portion.

2. A grille comprising splats, a molded ornament inserted between said splats, the outline of said ornament having a portion which bridges the space between them, and attaching means secured to the back of both, the splats and the ornament at said bridging portion, said means being such that it draws the splats together to squeeze the ornament between them.

3. A grille comprising splats, a molded or nament inserted between said splats and a staple whose cross-piece is secured to the ornament and whose prongs coact with the adjacent splats to pull them together against the ornament.

4;. A grille comprising splaiis, a molded ornament inserted between said splats, said ornament having a groove across its back and a staple whose cross-piece is forced into said groove, and whose prongs are entered into the splats.

5. A grille comprising splat s, a molded ornament inserted beh een said splats, said ornament having a groove across its back, and a staple whose cross-piece is forced into said groove, and whose prongs coact with the adjacent splats to pull them together against the ornament.

In testimony whereof, I have signed my name to this specification this 13th day of Jul 1915.
